I have an uncanny knack for dropping my car key under my car, usually at night. Inevitably, in these situations, I find that the flashlight I keep in my car has gone dim from drained battery power. This Auto LED stays forever charged in your car's cigarette lighter for those pesky moments when you need to read the details on a map, or find something that you've dropped under the seats or, in my case, under the car. The light's moon lens directs a bright circular beam where you point it, unlike the rather diffuse light I get from the tiny flashlight attached to my keychain.

The next time I go shopping for a new car, my number one priority will be multiple cigarette lighters so I can charge my flashlight, my iPod, my Garmin Nuvi GPS, and my cell phone all at the same time (okay, that's four, but I'll settle for three cigarette lighters).
